FINISHTNG WHEEL.

Application filed March 3, 1924. Serial No. 696,513.

This invention relates to finishing wheels and is illustratively shownVas embodied in a bufiing wheel designed for scouring the breasts ofVLouis heels.

The requirements of this type of Work necessitates wheels ofconsiderable size, sometimes as much as eleven inches in diameter, whichmay be run at -very substantial speeds. The resulting centrifugal forcehas made the types of wheel now in use. some of which are constructed ofwood and others of cast metal, unsatisfactory and dangerous. Trouble hasbeen experienced with the wooden wheels because of the insufficientstrength of the material itself. Moreover, such wheels have usually beenmade of sections pivotally connected to provide for replacement of theabrasive coverings and in the case of cast metal wheels, the inherentweight of the parts has rendered the locking devices for the twosections unsafe.

Accordingly, an object of the present invention is to provide aninexpensive construction which will be light and at the same time havevery considerable strength.

In the attainment of this object, the present invention provides animproved finishing wheel comprising, as herein illustrated, a sheetmetal body member having its flange transversely slotted to receive theends of an abrasive scouring or bufling strip which encircles theflange, the inner side of the flange being provided on one side of theslot with means to secure one end of the abrasive strip, and having astrip-tightening and securing member secured at the other side of theslot and carrying means to secure the other end of the abrasive strip.The invention also provides a locking member, illustrated as aspring-strip detachably secured atv its ends to the inner side of theflange, on the opposite sides of the slot, having projectionsconstructed and arranged to lock the ends of the abrasive strip againstthe inner side of the flange on the opposite sides of the slot bypressing against the tightening and securing member. In thisconstruction, lightness has been obtained without sacrifice of inherentstrength, and at the same time, the illustrated wheel has adequateprovision for detachably securing and locking the abrasive covering tothe wheel in such manner as to provide for convenient detachment andreplacement. i

In the accompanying drawings forming a part of this specification, l

F ig. l is a side elevation of a bufhng wheel to which an abrasive striphas been applied; i

Fig. 2 is a front elevation with the padding shown in section; and

Fig. 3 is an enlarged side elevation illustrating the method of applyingthe abrasive strip.

At the center of the cup-shaped member 10, which is. stamped from sheetmetal to the cross-section shown in Fig. 2, there is secured by screws14 a hub 18 having a flange 12. This hub has a portion 20 projectingthrough the metal cup for additional strength and is provided with setscrews 16 to hold the wheel on a shaft. The cupshaped member 10 has aperipheral flange 22 to which there is riveted a leather surface strip24 and surrounding this leather strip is a cushion member 26 which maybe formed of felt or any other suitable resilient material. This feltrim 26 has its external surface shaped in the desired cross-section andforms a backing for the abrasive strip 30 which entirely surrounds thewheel. It will be noted that the peripheral flange 22 of the wheelis-slotted at 32 to allow the-insertion of the ends of the abrasivestrip. At one side of this slot 32 and projecting inwardly from theflange 22 are two pointed pins 34. One end of the abrasive strip isforced over these pins, while the other end is then carried through theslot 32 and around the wheel and again brought through i? the slot 32 tobe fastened. In order to tight-` en the abrasive strip and secure it inposition, a hinged securing and tightening lever 36 is pivoted to theinside of the ange 22 on the side of the slot 32 opposite from the pins34. This lever has an end portion 38 which is designed to lie closelyagainst the inner flange 22 when the lever is swung adjacent thereto, asshown in Fig. 1. 0n the flat portion 38, there is provided a sharpenedpin 40 facing away from the slot. The end portion of the abrasive strip30 is brought around and over the pin portion 38 of the lever 36 andforced over the pin 40 When the lever is in its raised position, asshown in F ig. 3. The lever may then be depressed manually to tightenthe strip SO until the portion 38 brings the end of the abrasive stripagainst the flange 32, an aperture 4t2 being provided for the admissionoit the pin 40. This tightening lever is then heldin the latter positionby means of spring member 50 adapted to engage beneath hook members 54secured to the inner periphery of flange 22. rlhe hool; members 5d arepreferably formed by stanjiping in a portion of' the peripheral flange22 ot the sheet metal member lO. rlhis is best shown in Fig. 2. It lwillalso be noted from this ligure that the spring member 50, which is shownin dotted lines therein, is ot' substantial Width and has its endsslotefl :it to form projecting tabs 53 which are curved inwardly dengage the opposite sides of the hook meinbers 5d4 the better to retainthe spring member in position. The spring member 50 is provided,intermediate its enne, with tivo humps 56 and 58 which are arranged toengage the ends of the abrasive strip. The hump 56 bears against thestrip immediately adjacent to the flattened portion 38 and holds thestrip and the lever against the flange-22. rEhe other hump 58 pressesthe other end of the yabrasive strip against the flange 22 at a pointbetween pins 34. The manner of use of the bufiing Wheel will be apparentto those skilled in the art, it being obvious that it is intended to bemounted upon a power-driven shaft and the Work applied to the abrasivestrip which surrounds the periphery of a Wheel.

Having thus described. the invention, what I'claim as new and desire tosecure by Letters Patent of the United States is l. A finishing Wheelhaving a peripheral flange provided with a slot extending transverselythrough it, pins projecting from the inside off the flange at one sideof the slot to engage and secure one end of an abrasive strip Which ispassed around the Wheel and has its other end inserted through the slot,and a securing member for said other end of theslrip mounted on theinside of the flange at the other side of the slot and having astrip-engaging pin facing away from the slot.

2. A finishing Whe-el having a peripheral flange provided with atransverse slot, means mounted inside the periphery of the Wheeladjacent to one side of said slot for securingl one end of' an abrasivestrip which is passed around the Wheel and has its other end insertedthrough the slot, and a lever pivoted pon said flange upon its innerside adjacent to the other side of said slot and provided with asecuring member for said other end of the strip which member faces awayfrom the slot. Y

3. A finishing Wheel having a peripheral flange provided With atransverse slot, means carried by the inner side of the flange forengaging the ends of an abrasive strip vadjacent to either side of' saidslot, and a spring strip constructed and arranged to be d-etachablysecured at its ends to the inner side of the flange and to press againstthe ends of the abrasive strip to lock them detachably to said innerside on either side of said slot.
